3 Models: IUC-X9-TXC & IUC-7X-RXC Manufacturers of Process Controls and Instrumentation Telephone Line Transmission System (Formerly: IUC-29-LIN-FRC & IUC-72-UNV-FRC) Standard Features: High Input-Output-Power Isolation (1500VAC Test) Industry Standard Inputs: 4-20 ma, 1-5 VDC, and more (see below) Industry Standard Output: 4-20 ma, 1-5 VDC, more (see below) Send One Analog and Two Contacts over Class C Telephone Line Easy Field Calibration Microprocessor Controlled for High Accuracy Two Wire Supply Option for Two Wire Transmitters Power: 117 VAC 50/60 Hz (Optional 24 VDC) High Noise Rejection CSA and NRTL Approved (LR 51078) R Function: NRTL/C Model Designation: IUC-X9-TXC IUC-7X-RXC The IUC-X9-TXC is a telephone line transmitter which takes in one analog signal and two dry contacts. It has a 600 Ohm impedance matched output which can connect directly into a class C telephone line. All three signals are sent simultaneously to the IUC-7X-RXC telephone line receiver where they are split up into their original forms. The IUC-7X-RXC also has an impedance matched input to allow direct connection to the phone line. A built in line monitor detects line failures and sets the output to 4 ma. Input 1: 1-5 ma (Zin=1K Ohm) 2: 4-20 ma(zin=250 Ohm) 3: 0-1mA (Zin=5K Ohm) 4: ma (Zin=100 Ohm) 5: 1-5 VDC (Zin=1Meg Ohm) 6: 0-10 VDC (Zin=1Meg Ohm) 7: Special Input Output 1: 1-5 ma (4000 Ohm Drive) 2: 4-20 ma (1000 Ohm Drive) 3: 0-1 ma (20000 Ohm Drive) 4: ma (250 Ohm Drive) 5: 1-5 VDC (Zout=250 Ohm) 6: 0-10 VDC (Zout=500 Ohm) 7: Special Output Example: A Transmitter/Receiver pair for 4-20 ma input and output with 2 dry contacts in a standard metal enclosure is designated by IUC-29-TXC and IUC- 72-RXC. If no options specified, unit is 117 VAC Power in metal enclosure Specifications: Isolation: Input to Output to Power 1500 VAC (Test) Accuracy/Linearity:+/- 0.3% max., +/- 0.1% typ. Operating Temperature: -40 Deg.C. to + 50 Deg.C. Temperature Effects:+/- 0.5% max., +/-0.2% typ.
